Wayne Rooney has opened up on the angriest he ever saw Sir Alex Ferguson at Manchester United.

Ferguson led United to unrivalled dominance across his trophy-laden 26 reign at Old Trafford and that success, combined with his managerial brilliance, was underpinned by a fierce approach - the 'hairdryer treatment' has been well documented by players.

Despite Roy Keane being trusted as Ferguson's United's captain for eight years, the Irishman received no special treatment from Ferguson, however, after a few fallouts with the legendary former boss, one disagreement in 2005 proved to be the last between the pair.

Keane dramatically left United that year following his final fall out with Ferguson and Rooney has reflected on the incident.

"When Roy Keane left the club, I think it's well known, there was a meeting," Rooney told the Tony Bellew Is Angry podcast.

"I can't say the details of the meeting, but obviously Roy Keane's had a go at some of the players on the club's TV channel and Fergie weren't happy so he calls up a meeting and he wants us to all watch it together.

"So, we've all gone into Alex Ferguson's office, the coaches, Alex Ferguson and the whole squad. I was 18 or 19 at the time, we've all watched this and Roy has asked any of the players if they have a problem and everyone said no - to be fair, it wasn't bad.

"It was obviously hangover of something that gone on between Roy and the manager in the past probably. It's gone into an argument between Roy and the manager and a few different things got said and I saw Alex Ferguson jump over his desk.

"I was just thinking 'wow this is crazy'! He jumped over the desk and he's getting held back. It got calmed down, but the next day Roy Keane has come to training and about 30 minutes later we saw him driving off and was the last we saw of him."
